Waste Reduction Targets and Performance

The Daiichi Sankyo Group defines zero emissions for waste as the final disposal rate representing less than 1% of the total amount of waste.

At our plants and research centers, the Group has established waste reduction and resource efficiency as important issues. Consequently, we seek to save resources through efforts such as the streamlining of resources used in manufacturing and packaging processes, the comprehensive separation of unnecessary and waste materials, the reduction of the total volume of unnecessary and waste material, and resource recycling. Whenever possible, the Group chooses waste disposal firms that recycle thoroughly. We continued to promote our resource recycling policy in FY2020, and the recycling rate (the percentage of the amount recycled from the total amount of waste generated) increased from 32.2% in FY2015 to 42.0% in FY2020. This is due to an increase in the production of products that generate byproducts that can be recycled.

At each office, we promote the thorough separation of trash, double-sided printing of office paper, paperless operations and other measures. At the G20 Osaka summit held in June 2019, plastic waste was discussed as one of the most important topics. We are addressing the plastic waste issue by changing materials for packaging and handouts, such as briefing materials and employee mobile cards.

The total amount of waste generated in FY2020 decreased by 277 tons which was effectively almost at the same level as the FY2019. The final disposal volume increased by 64 tons, and the Group maintained its zero emission with a final disposal rate of 0.65%.

Promotion of Waste Compliance

Based on the 5-Year Business Plan, our environmental auditing at plants, research facilities, offices, and other operation sites focuses on verifying the level of compliance with the Waste Disposal Act as part of our efforts to prevent inappropriate waste disposal. Additionally each operation site regularly conducts on-site inspections for waste management contractors (in terms of their level of compliance with applicable laws and regulations, contract implementation, permits and licenses, actual waste disposal operations, etc.).

All operation sites of domestic Group companies have introduced electronic manifests since FY2016 with the goal of reducing risks pertaining to waste disposal.

Efforts to Reduce Waste

Reduction of office paper use

We promoted our efforts such as promoting double-sided printing and N-up printing, reducing distributions of printed documents (promoting paperless operations by using personal computers and projectors), putting up posters to encourage reductions in printing, and using IC card authentication to prevent printing errors. As a result, the amount of office paper used in FY2020 was 2.75 million sheets, a 36.4% decrease from FY2019, and we are continuously promoting effective use of office paper.

Promotion of 3Rs (Reduce, Reuse, and Recycle)

Promotion of reuse within the office

We promote reuse of stationery by placing “stationery collecting trays” at the Headquarters area, the Shinagawa R&D Center, and the Kasai R&D Center. Both R&D centers collect not only stationeries but also reusable devices and equipment, and display them in the “Exhibition Room for Reuse” to encourage recycling. In addition to proactively making announcements on the new lineup of goods for exhibition, the R&D centers share and exchange their lineups.

Reuse of recovered organic solvents

At the Odawara Plant of Daiichi Sankyo Chemical Pharma Co., Ltd., we reuse collected organic solvents in manufacturing processes within the company after purifying them through an external contractor.

Promotion of recycling

At the Hiratsuka Plant of Daiichi Sankyo Propharma Co., Ltd., we recycle work clothes and latex gloves used in the pharmaceuticals manufacturing process.

Closed-loop Recycling Efforts

In December 2020, we launched an initiative at our special subsidiary Daiichi Sankyo Happiness’s Hiratsuka site to achieve closed-loop recycling* in order to contribute to the realization of a recycling-based society through employing disabled people. In the initiative, Daiichi Sankyo Happiness sorts office paper and other trash produced at the Hiratsuka site, which is used by both Daiichi Sankyo and Daiichi Sankyo Propharma, to be recycled. Six months of office paper, approximately 11,110 kg, is recycled into about 30,000 rolls of toilet paper to be used at the site, enough for one year of use. We will continue working to solve social issues and contribute to the realization of a recycling-based society through employing disabled people.
Toilet paper made from recycled paper is also given as a prize in the Daiichi Sankyo Group COOL CHOICE Program.

* Materials recovered from used Daiichi Sankyo products are reused in Daiichi Sankyo products.
